In this lesson, students will be introduced to how the Doppler effect changes our perception of wavelengths of sound (pitch) and light (color). Students will model how astronomers use the line spectra of stars to identify elements in the stars and...(View More) the speeds of galaxies in the universe. Requires some special equipment for spectral analysis and a darkened room for viewing spectra. Suggestions are included for introducing the Doppler Effect for students unfamiliar with this concept. This activity is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1929 Cosmic Times Poster.(View Less)

This is a lesson about ice worlds in the outer planetary regions and the role they play in understanding the Solar System. Learners will role-play stories connecting science-related literature to ice worlds, view and interpret space-based images of...(View More) ice worlds, and investigate surface and interior features of outer planetary ice worlds. Photometry and spectroscopy will be used as background. Activities include small group miming, speaking, drawing, and/or writing. This is the lesson 11 of 12 in the unit, Exploring Ice in the Solar System.(View Less)

This is a lesson that sets up the final project for the Astronomy unit. Learners will research the requirements for human survival and analyze the planets and moons in our solar system to assess the ability of each to support human survival. The...(View More) lesson models scientific inquiry using the 5E instructional model and includes teacher notes, prerequisite concepts, common misconceptions, student journal and reading. This is lesson 12 in the Astro-Venture Astronomy Unit. The lessons are designed for educators to use in conjunction with the Astro-Venture multimedia modules.(View Less)
